 The standard math header included here - '''<cmath>''' - does not inject
 math functions into the global namespace. The only standard way to use
 these functions (pow included) is via std:: namespace.

 All the uses of pow should be converted to std::pow, otherwise compilers
 with strictly conforming standard headers (like SunCC) will not be able to
 compile.

 std::pow works fine with all the compilers I tried (SunCC, g++).

 (suggested patch attached)
